I purchased an Atari Speakerhat for detecting on all the days other than cold weather. Keep the sun off my head, hear the beeps, not cover my ears from ambient noise.

The technology inside consists of proprietary high-fidelity stereo speakers and microphone, V 4.1 CSR/Qualcomm® cVc™ audio technology, 5-band EQ, Advanced Audio Distribution Profile (A2DP), Audio/Video Remote Control Profile (AVRCP v1.4) and Headset Profile (HSP v1.2), rechargeable lithium Ion battery, universal control button, and LED indicator light.
You can also interface to your phone for calls, music, etc. Awesome.
